This article presented the nursing experience of taking care of a twenty-year-old young man with Tourette's disorder who was admitted due to severe self-injuring behaviors. During the hospitalization, the authors collected data based on conference and skills of observation and using Gordon's 11 Functional Health Patterns to delineate the patient's health problems including high dangerous self-injury, dysfunction of self-response, absence of capability of his family members' management, and existing damage and inability to take care of himself. The authors established a good nurse-patient rapport during the nursing care. We provided the patient and his family members with relevant nursing guidance in addition to emotional support. We also applied Habit Reversal Therapy (HRT) involving the patient and his family members, which resulted in improvement of the patient's self-injuring behaviors and establishment of his self-confidence. The patient was then smoothly discharged back home.
